Best Sony NEX-6 Memory Card

The Sony NEX-6 can use two different types of memory cards. Sony PRO-HG Duo and PRO Duo can be used in plus SDXC, SDHC, and SD cards.

The camera only has one card slot. You'll need to make a decision between an SD or PRO Duo card.

PRO Duo cards are a proprietary memory card format owned by Sony. Because of this, SD memory cards are cheaper and can have greater performance than PRO Duo cards.

In a rush? My unbiased and professional recommendation is this SD memory card for best performance of the NEX-6:

SanDisk Extreme Pro UHS-I SDHC Memory Card

SanDisk Extreme Pro 32GB SDHC Memory Card

64GB or larger cards are not compatible with the camera.

Best SD Cards

High-quality producers of SD memory cards include Lexar, SanDisk, and PNY. The more reliable SD memory cards I have owned have been the SanDisk Extreme Pro memory cards.

That does not mean you need to purchase a card from SanDisk for your Sony NEX-6. Just make sure the name sounds cool. That will make sure you get faster read/write speeds, water resistance, and more features.

I have not run into problems with PNY Elite Performance or Lexar Professional memory cards.

When I have experienced problems with cards has been when low priced generic brands were used. Not having a brand name boosts the possibility of data corruption or memory card errors.

If you would like to spend less, don't buy a generic card. You will be better off buying a professional-quality memory card with a reduced storage capacity.

Sony NEX-6 SD Card Compatibility

SD, SDHC, and SDXC memory cards can be used with the Sony NEX-6. If you want to get the best performance, use a card.

The newest SDUC memory cards are not supported by the NEX-6.

There are four different specifications of Secure Digital (SD) cards. New card specs add tech that allows for increased storage capacity as well as much faster data transfer speeds.

  • Secure Digital (SD) - 128MB to 2GB.
  • Secure Digital High Capacity (SDHC) - 4GB to 32GB.
  • Secure Digital eXtended Capacity (SDXC) - 64GB to 2TB.
  • Secure Digital Ultra Capacity (SDUC) - 4TB to 128TB.

SD Card Speed

The speed rating of an SD memory card is dependant on the sequential read and write speeds. Memory card file write speed is essential for video and continuous shooting.

Slows SD cards can cause a decrease in the number of continuous photos the Sony NEX-6 can capture. This is because the camera's buffer is not able to write data to the card quickly enough.

When shooting video, a slow memory card can cause an abrupt end to recording. The video file might also end up being corrupted. If you are going to capture video, it is important the card you use meets the requirements of the camera.

Card read speed is nice to have for file transfers to a computer. If you are filling up cards with images or video, a card with a fast read speed will cut down on the transfer time.

Speed Class Rating

Example of where to find SD Card Speed Class
10 inside of a C showing that the SD card is Class 10.

The Sony NEX-6 needs at least an SD memory card that has a Class 4 rating.

The continuous write speed establishes the Class rating that an SD card gets. Class 10 is the highest rating which is given to cards that have a write speed greater than 10MB/s.

  • Class 2 - 2MB/s
  • Class 4 - 4MB/s
  • Class 6 - 6MB/s
  • Class 8 - 8MB/s
  • Class 10 - 10MB/s or faster

Every brand name SD card that you can buy online will have a Class 10 rating. To find the class rating of a card, look for a number inside of a C on the label.

Ultra High Speed (UHS)

Example of an SD memory card with a UHS-I rating.
This card has a UHS-I rating. UHS-II and UHS-III cards will have II or III, respectively.

The Ultra High Speed (UHS) bus can be found in SDUC, SDXC, and SDHC cards. UHS memory cards to achieve faster read and write speeds.

Three separate specifications exist. They are UHS-I, UHS-II, and UHS-III.

Look at the front of the memory card to find the rating of a memory card. If the memory card has UHS, a Roman numeral I, II, or III can be seen on the front of the SD memory card.

  • UHS-I - Maximum transfer rate of 104 MB/s
  • UHS-II - Maximum transfer rate of 312 MB/s
  • UHS-III - Maximum transfer rate of 624 MB/s

Sony NEX-6 PRO Duo Card Compatibility

The Sony NEX-6 can use a single PRO Duo or PRO-HG Duo cards. PRO-HG signifies the memory card may have read speeds up to 50MB/s and a 15MB/s minimum write speed.

You'll need to pay double to get a PRO Duo card than an equivalent SD card. Considering the price difference, I will not recommend purchasing a Sony PRO Duo card for use in a NEX-6.

Image Capacity

  • 32GB - 9,280 images
